@@turboconqueringmegaeagle9006 As a suggestion why not try vibrating on top after the water totes are on? Solid wood to transfer the energy straight into the pipe.
I think the ground pressure on the sides of the pipe are starting to become significant relative to the tip pressure, so the pipe is acting as a giant pile rather than floating. The differing water levels on either side of the pipe indicates that there's quite a bit of ground in direct contact. Water blasting soil from the sides earlier to level out the pipe probably helped in more ways than you thought.
You Could drill some weep holes through the pipe to drain the water to the inside. Then plug them later. Or pound some shallow sand point wells around it, and try to pull the ground water out that way, may be a better option if it worked. I don't think its a buoyancy problem, I think it maybe the wet soil hydraulically clamping around the column. Think of the same phenomenon that pushes retaining walls over.
Heaving, that would make sense. You are echoing many of the other comments, I know my buoyancy calculations are wrong because it never should have got as far as it has.
Hey James, this is Eric, formerly Vigilante. What about making a couple of giant soil vibrators and drop them down into the external muck. This might make the muck less viscous, thus inducing the pipe to slide more readily? Just a thought buddy. Keep it up! Yours is my favorite Chanel and I tell everyone I meet about your endeavors and genius.
If there's water on the inside and outside, even if they're not connected, the lower cylinder will float. I think. The flotation is equal to the amount of water displaced, so if you know the dimensions of the cylinder (Outside cylinder volume - inside cylinder volume = volume of concrete in pipe) (then convert to gallons, then multiply by 8 to get lbs), you'll see that each cylinder displaces X amount of water, which is equal to your buoyant force. There seem to be tables available for every concrete pipe size which show at least the dimensions if not the volumes, I'd be surprised if the flotation # isn't a known value already. This is why I love your channel though, always an interesting engineering problem to think about! Edited after watching more: if you've dug enough that the outside water is washing into the hole through those sand channels, and you've pumped it out, there is no flotation, it's just the friction on the sides of the hole. Even if there's water still on the outside, trapped in pockets against the cylinders, it won't be providing any buoyant force. Also, if you know where I can get an application for the Hole Appreciation Society...
I've found plenty of tables ect. But they all talk and going into "liquidouse matter" not going through and coming out the other side, from my calculations the force exerted on the liquidouse section (between the 6' and 12' mark) with a 1.5m od is 11 ton of force which means it never should have gone down as far as it has which is making me doubt everything! I hate doubt, much rather balls things up and at least understand it than be in this limbo so given this and the other sensible comments I've had, I'm just going to find a lot more weight to sit on top and see what happens. Hole appreciation society have cut all ties with me now, apparently I'm not the sort of rif raf they want associated with them.
Disappointment is a major part of progeress my friend...You're getting there James, just look at how far you've came from when you started out and imagine yourself feeling that same way when you've finished the pipe drop. Faith brother... *FAITH* !
It seems to me that I made a similar digging tool to yours back in the late 70's. It worked alright, but the handle bent since it was electrical conduit.
Take the boy to work day? Keep going, it does look like hard work though. What you could do with is a tank on the ground to drain the other tanks into so you don't rack up a huge water bill.

Thanks for your new video. Don't feel obligated to only post a video if two concrete sections have been placed. The unexpected side effects are also interesting. Also from a technical point of view. Despite the new 'challenges' you are doing well. You have my support. :)
I'm glad you are finding it interesting, the two pipe rule is really for my own motivation to get this done asap as this is merely the prelude to the really fun stuff.
pick up an old bench grinder, strap it to the concrete pipe, then put an off center weight on one side, plug it in and turn it on... your vibration didnt work because you were vibrating the mud, which absorbs vibrations... you have to vibrate the solid pipe
Your videos are amazing brother, Love watching! Can you explain the process of digging horizontally and how large rooms are going to be supported/shored up underground?
Cheers mate, I'm going to use the Brunel method of a metal "digging shield" which will also cut the clay to shape and press against the pre cast concrete ceiling and walls keeping pressure on them and preventing movement. I did a blackboard video 6 months or so ago explaining the process a little better than I can here in the comments.
It looks like your time at the TCME gym and spa (weight training, stair climbing, and mud baths...LOL ) is working and producing results for you and the project. Good luck and stay safe also great video.
It seems if you vibrate, that will also consolidate the earth around the outside of your column making the problem worse. Also with regards to the earth holding the column (if hydraulic suction on the outside is the problem). The weight will be more and thus more suction at the lower end of the column. You noticed downward movement of the column when you pumped water on the outside.
You could also spray the inside of the pipes with Tomsons water seal its silicon-based and the best stuff don't be conned with other stuff, I was conned once
I don't care if you have not gotten as far as you wanted. that doesn't ruin the video... If stuff gets tough and things start changing the plans from the original idea that is stuff we want to see and hear! if you have trouble sinking the pipes in there maybe there is someone who understands these forces better and can give you a bit of advice to make it easier. AvE always says "How do you find out how to do something the right way? You tell the internet you did it the wrong way and you will have 10% of the viewers screaming the right way to do it at you!" I might even use some high pressure water on the outside there to dig a channel down the side to reduce any forces. IF you have a channel along the side of the pipe anything can squeeze around and up out of it instead of pushing back onto the pipe. Keep up the bomb ass work lol
Is there any pipe jacking technique other than placing weight on top that might work? You could only place so much force on the pipe column. A tough problem now you are almost there.
Just realised I have some stuff that would probably be useful to you. I have some of the MOD impervious membrane that I bought at auction from RAMCO in Skeg. I have 4 rolls that you can have. It's got a lightweight interwoven metal grid inside it you can form it into shapes, it's quite sturdy stuff and you could lay it down so you don't have to paddle around so much. It's 1.5m wide and I think they are 10m long each.
@@turboconqueringmegaeagle9006 Oh have I? LOL. I've slept since then. I'll just sign up to your patreon instead. If you need any electrical bits and bobs let me know.
It seems more like a suction thing than a buoyancy thing like getting your muck boots stuck and not being able to get them back out but in reverse if you dont have a powerful enough pump could you stagger pumps to pump the water out as long as the gpm or lpm are the same so as not to run a dry pump
I'm a little confused by it all, my calculations suggest there is more buoyancy than weight which means it never should have got down as far as it has so I'm definitely wrong however any buoyancy I remove is less weight I have to add up top but it's so unpleasant digging in that 1' wide trench that I'm happy to abandon it and try everything you guys have suggested!
No worries man I know how Topsy turvy doing work can get especially stuff like that where you're learning as you go even if you stop now though you've got Colin furze beat for coolest man cave
Heya, looking good as always. Gotta say I’m watching thinking this isn’t a floatation problem, from the little I know I thought that the buoyancy point needed to be above the water plane. As your liquids are effectively on the side surely this isn’t creating a buoyancy effect? It looks more like the clay surrounding the pipe is acting like sticky blue tack and traction is keeping it up. Have you considered cutting a small channel through the dirt from inside the pipe under pipe section ones lip (effectively the outside of the pipe section) up till it meets the water your trying to get out? This could flood your inside but surely this would be easier to deal with? Also.this would give you a drainage channel which would gradually increase (hopefully) in size as more liquid passes through - giving you less contact area between pipe and dirt although I’m not sure how much less friction this would give you long term.
I'd considered drilling a hole through the pipe in desperation. You have used the phrase buoyancy point, that's not something I came across in any of my reading, I've obviously not read enough. Absolutely any advice welcome, I'm not enjoying digging down beside the pipe so maybe more weight up top.
@@turboconqueringmegaeagle9006 buoyancy point is a bit like centre of gravity but i think refers to the centre point of displacement / upforce? (Just checked - the central point of mass below water level) if the water is to the side , it’ should not be causing floatation. I think you were on the right track pouring water down the outside and sucking it up from the inside, using soil erosion seemed to be working. Maybe look at some videos on digging holes with water? Also has the recent couple of months on and off bad weather caused the ground to swell? This could be causing a clamping effect around the pipe?
A much bigger tub! Then an automated tub, then several automated tubs.... Maybe. I need speed things up or I'll die an old man before I've even got room for a small lathe down there.
So watched it all. Kudos on your determination! Can your new air compressor support 85ish cfm at 95-105 psi if so probably an air Venturi pump would work. Blow all that crap out, little stones and all. As for your clay it looks fairly wet, bentonite clay you that you buy for well plugs, ponds etc will have much better expansion to create a better seal. ( I live in western wa US) our two properties have a clay layer one 2’ and the other 3.5’ and I just use it for a base fill for new roads on the properties and cover it right away with 1’+ of pit run. It turns to slick shit real quick whenever i try to save it for a pond etc. awesome to see your little one rallying with you on the dump truck btw👍🏻
Yes mate, that's a bloody good idea, she'll only make about 30cfm but that could still work I'll give it a go. I spent all summer working in a slaughter house with a "tornado" system, don't know why it took you suggesting that for me to join the dots but thank you.
Could you not put timbers across the top rig a chain across it, and along with a pulley system direct the force downward when hooked up to a Tractor (Maybe) , surely that would exert more than 2 tonnes of downward force? I dunno , you're the expert, it was just a thought
I'm no expert mate, all your ideas are golden, I had thought about using my truck somehow but it's important to get any load going straight down or I'll crack a pipe.
Awesome video mate and thank you so much again for the mention! Im loving these digging videos, you are doing so well. I was trying to do some research for you on the buoyancy problem and couldnt see clearly the exact markings or your concrete rings. Are they 1200 x 750mm? And i think you mention they are 300kg but i cannot see any that ‘light’, the ones i can find are more like 685kg. Do you know the weight of each? Edit… ive just seen 660kg on a ring! Fyi we are driving to Spain at the weekend! God knows when all my workshop tools and stuff will arrive but we are making progress at least… Another edit… I remember fred dibnah used to use horizontal spikes between some courses of bricks, id assumed this was to hold the bricks up but i wonder if its equally good at keeping the tunnel from rising up too.
1200 (id so 1400 od) x750 and 700kg so they displace more than their own weight, I've only found info that talks about working within the water table not what happens when you get through the other side, right now I'm thinking the relief boring is unpleasant and unnecessary and I should stick another 2 ton on top. Have you bought a place then or are you going out to nose around before hand? Exciting times my friend.
Maybe the weight of the water inside is compacting the bottom so making it harder for the pipe to drop. The displaced soil has to go somewhere so maybe it's rising up the centre a bit but the weight of the water is fighting it. IGNORE that think it is probably bollocks.
It's bloody hard packed clay down there mate, I'm pretty sure I'm chatting bollocks too so join the club, I'll stick another few tons on top I think, digging down the side has been absolutely horrible.
@@turboconqueringmegaeagle9006 yeah that looks like a mugs game mate. Would take a bit of balancing but those ibcs take forks what about two steel beams across the pipe top and an IBC on either side as well as one in the middle? There is only so high you will be able to go with them!
So many things to comment on in this vid. I think the overwhelming one mate is your tenacity and hard work. Fk me, I'd be dead by now trying to do a 10/th of the effort I can see you are putting in. Can't say how Impressed and how much I admire that. You don't show a lot of the hard work but just between the clips it's easy to see for those of us that have done hands on stuff just how much effort this is taking. I Think your craftsmanship, skill and problem solving is brilliant but for me it pales into comparison of the sheer effort and resilience you have doing this. Seriously, if ever you need to find a New Job, show the employer this vid. I have run businesses and if someone said this is my resume, it would be the last one I'd look at and you'd be hired then and there. Says loads about the man you are and definitely the sort of bloke I'd want with me. When you were talking about the weight on the pipes, an IBC was what I thought of. That fact that's what you did gives me comfort a smart man had the same Idea..... although I didn't think of stacking 2 but shows you are also braver than I. I think you can stack 4 of them in their weight rating... But I wouldn't recommend that in this case. :0) One thing I did think of with the digging particularly horizontal, would be to use an Auger. I have a petrol Post Hole Digger and boring a load of holes like a Swiss Cheese and then breaking the walls out between I have found is much easier for me than just digging with a shovel. If there was a Drill for your Hydraulic pump, that may be worth considering. That said. I was amazed in the shot of you digging the clay. Sounded like you were digging Concrete! You won't need to reinforce the Tunnel walls. Just light a good hot fire and bake them and you will have Terra cotta! Far from a disappointing vid mate. Awe inspiring for me in your creativity with problem solving and the sheer bloody effort resilience you have. Fking champion in my book!
I don't think 4 ibc's is a problem, on the contrary I think it'd be fun trying! I'll try and pick a few more up this week, maybe get some extra so I can pump between them rather than using a hose pipe as that takes a while. Thanks as always for your motivational words and plugging my channel, it means a lot my friend.
- It's not flotation. Looks like you hit a relatively solid strata. - seems to me the easiest way to drain the water from outside the casing is to drill a small channel parallel to the casing deep enough for water pressure to break through and drain to the interior, where you can run the pump.
F*$King trains lol .I think that sump turned out well James and the more you do the better you will get so I think you should do all your castings instead of buying them in all ready made as it will be cheaper and every penny saved. Things really seem to be moving on quickly now it's amazing that you have achieved all this single handed. You really are one of akind James keep it up mate your doing what many can only dream of. Take care till next time my hero. 👍👍👍
I suppose if I made the sumps in two parts I could make permanent moulds, it's time though mate, just slipping through my fingers, can't believe we're approaching august.
with the pressure pump you are building what you use is air not water the air acts as a piston and each bubble carries water with it and it will carry the rubbish with it or you could use a clam shell
It's a technically challenging idea but the ground at the bottom is very solid and I have a 3 ton come-along, one of craziest ideas that I think would actually work so far, nice one.
@@turboconqueringmegaeagle9006 nice one! A 3 Tonne would be a right pull. I see theres such a thing as a ground anchor auger might give a good enough hold if it can be drilled in.
Go drop one of those rings in a river M8 see if it floats LOL if it does see how long before it sinks if it floats its that porous it woulda crumbled by now M8 it ain't made of pumice I hope
Entire video I sat here going "What in the fuck is he doing? Why IBC totes on TOP of it? This guy is so dumb...?" Then I realize you're smarter than me. Well done, sir.
@@davidevans4750 yeah that's a nice bunker, can't remember the bitumen, I'll have to rewatch it. My favorite bit of that build was his muck removal railway, really cool.
Could you not jerry-rig some sort of slide-hammer off those lifting mounts you already have in every one of those pipes, leave it going like some nodding donkey?
@@turboconqueringmegaeagle9006 I should clarify that I meant it as more of an agitator/vibration than a give it some welly type of thing with it being concrete :D
You have me baffled, You think those rings want to float? not a chance you need to get a slew or 360 machine and a bloody good driver dig round the rings you ain't gonna puddle th clay round them till your down t lvl and water pressure won't stop em sinking.
I was reading straight from the American association of concrete pipes, and my pipes definitely displace more than they weigh. Either way even if it's just for the backfill, I need the water gone at some point.
@@turboconqueringmegaeagle9006 If they were led flat maybe but not vertical M8 I put god knows how many of those rings in the ground I ain't wrong. if you dig round those rings as you shoulda done from the start you could fill that extra-large hole with water and those rings would sink to the bottom no problem and you said you were gonna puddle blue clay round the finished job for waterproofing

If stuff gets tough and things start changing the plans from the original idea that is stuff we want to see and hear! if you have trouble sinking the pipes in there maybe there is someone who understands these forces better and can give you a bit of advice to make it easier. AvE always says "How do you find out how to do something the right way? You tell the internet you did it the wrong way and you will have 10% of the viewers screaming the right way to do it at you!" I might even use some high pressure water on the outside there to dig a channel down the side to reduce any forces. IF you have a channel along the side of the pipe anything can squeeze around and up out of it instead of pushing back onto the pipe. Keep up the bomb ass work lol
Exactly what I’m thinking. Ram some 1” pipes down along the concrete to equalize the pressure.
Always, you guys have put me on the straight and narrow more times than I can remember and I'm grateful.
Im still baffled M8, water in that situation is a lubricant
Is there any pipe jacking technique other than placing weight on top that might work? You could only place so much force on the pipe column. A tough problem now you are almost there.
Lots of good advice and ideas, she's moving again now and I've still not broken anything so fingers crossed it goes smoothly now
You never disappoint my friend.
My Mrs disagrees but thanks mate!
Just realised I have some stuff that would probably be useful to you. I have some of the MOD impervious membrane that I bought at auction from RAMCO in Skeg. I have 4 rolls that you can have. It's got a lightweight interwoven metal grid inside it you can form it into shapes, it's quite sturdy stuff and you could lay it down so you don't have to paddle around so much. It's 1.5m wide and I think they are 10m long each.
Youve offered before my friend, I'm just not sure how I'd use it
@@turboconqueringmegaeagle9006 Oh have I? LOL. I've slept since then. I'll just sign up to your patreon instead. If you need any electrical bits and bobs let me know.
@@davenorth1265 I'm almost certain I'll take you up on that offer, if not I'll definitely be needing some advice thank you mate.
It seems more like a suction thing than a buoyancy thing like getting your muck boots stuck and not being able to get them back out but in reverse if you dont have a powerful enough pump could you stagger pumps to pump the water out as long as the gpm or lpm are the same so as not to run a dry pump
I'm a little confused by it all, my calculations suggest there is more buoyancy than weight which means it never should have got down as far as it has so I'm definitely wrong however any buoyancy I remove is less weight I have to add up top but it's so unpleasant digging in that 1' wide trench that I'm happy to abandon it and try everything you guys have suggested!
No worries man I know how Topsy turvy doing work can get especially stuff like that where you're learning as you go even if you stop now though you've got Colin furze beat for coolest man cave
Heya, looking good as always. Gotta say I’m watching thinking this isn’t a floatation problem, from the little I know I thought that the buoyancy point needed to be above the water plane. As your liquids are effectively on the side surely this isn’t creating a buoyancy effect? It looks more like the clay surrounding the pipe is acting like sticky blue tack and traction is keeping it up.
Have you considered cutting a small channel through the dirt from inside the pipe under pipe section ones lip (effectively the outside of the pipe section) up till it meets the water your trying to get out? This could flood your inside but surely this would be easier to deal with? Also.this would give you a drainage channel which would gradually increase (hopefully) in size as more liquid passes through - giving you less contact area between pipe and dirt although I’m not sure how much less friction this would give you long term.
I'd considered drilling a hole through the pipe in desperation.
You have used the phrase buoyancy point, that's not something I came across in any of my reading, I've obviously not read enough.
Absolutely any advice welcome, I'm not enjoying digging down beside the pipe so maybe more weight up top.
@@turboconqueringmegaeagle9006 buoyancy point is a bit like centre of gravity but i think refers to the centre point of displacement / upforce? (Just checked - the central point of mass below water level) if the water is to the side , it’ should not be causing floatation.
I think you were on the right track pouring water down the outside and sucking it up from the inside, using soil erosion seemed to be working. Maybe look at some videos on digging holes with water?
Also has the recent couple of months on and off bad weather caused the ground to swell? This could be causing a clamping effect around the pipe?
Yay! Been waiting for the next episode! Awesome work man, keep it up!
Cheers mate
You keep talking about getting rid of the tub, but what are you gonna use for removing dirt once you start going horizontal?
A much bigger tub! Then an automated tub, then several automated tubs.... Maybe.
I need speed things up or I'll die an old man before I've even got room for a small lathe down there.
Great update, thanks.
Cheers mate
Hell ha!!!! Thanks James, I’ve been waiting for this video. I haven’t seen it yet but I will, comment again shortly👍🏻
So watched it all. Kudos on your determination! Can your new air compressor support 85ish cfm at 95-105 psi if so probably an air Venturi pump would work. Blow all that crap out, little stones and all. As for your clay it looks fairly wet, bentonite clay you that you buy for well plugs, ponds etc will have much better expansion to create a better seal. ( I live in western wa US) our two properties have a clay layer one 2’ and the other 3.5’ and I just use it for a base fill for new roads on the properties and cover it right away with 1’+ of pit run. It turns to slick shit real quick whenever i try to save it for a pond etc.
awesome to see your little one rallying with you on the dump truck btw👍🏻
Yes mate, that's a bloody good idea, she'll only make about 30cfm but that could still work I'll give it a go.
I spent all summer working in a slaughter house with a "tornado" system, don't know why it took you suggesting that for me to join the dots but thank you.
Could you not put timbers across the top rig a chain across it, and along with a pulley system direct the force downward when hooked up to a Tractor (Maybe) , surely that would exert more than 2 tonnes of downward force?
I dunno , you're the expert, it was just a thought
I'm no expert mate, all your ideas are golden, I had thought about using my truck somehow but it's important to get any load going straight down or I'll crack a pipe.
Awesome video mate and thank you so much again for the mention! Im loving these digging videos, you are doing so well. I was trying to do some research for you on the buoyancy problem and couldnt see clearly the exact markings or your concrete rings. Are they 1200 x 750mm? And i think you mention they are 300kg but i cannot see any that ‘light’, the ones i can find are more like 685kg. Do you know the weight of each? Edit… ive just seen 660kg on a ring! Fyi we are driving to Spain at the weekend! God knows when all my workshop tools and stuff will arrive but we are making progress at least…
Another edit… I remember fred dibnah used to use horizontal spikes between some courses of bricks, id assumed this was to hold the bricks up but i wonder if its equally good at keeping the tunnel from rising up too.
1200 (id so 1400 od) x750 and 700kg so they displace more than their own weight, I've only found info that talks about working within the water table not what happens when you get through the other side, right now I'm thinking the relief boring is unpleasant and unnecessary and I should stick another 2 ton on top.
Have you bought a place then or are you going out to nose around before hand? Exciting times my friend.
Maybe the weight of the water inside is compacting the bottom so making it harder for the pipe to drop. The displaced soil has to go somewhere so maybe it's rising up the centre a bit but the weight of the water is fighting it. IGNORE that think it is probably bollocks.
It's bloody hard packed clay down there mate, I'm pretty sure I'm chatting bollocks too so join the club, I'll stick another few tons on top I think, digging down the side has been absolutely horrible.
@@turboconqueringmegaeagle9006 yeah that looks like a mugs game mate. Would take a bit of balancing but those ibcs take forks what about two steel beams across the pipe top and an IBC on either side as well as one in the middle? There is only so high you will be able to go with them!
Surely you just need to spray wd40 on the outside of them :)
@@DansKoiPond only so high I can go with them? Challenge accepted.
So many things to comment on in this vid. I think the overwhelming one mate is your tenacity and hard work. Fk me, I'd be dead by now trying to do a 10/th of the effort I can see you are putting in. Can't say how Impressed and how much I admire that. You don't show a lot of the hard work but just between the clips it's easy to see for those of us that have done hands on stuff just how much effort this is taking. I Think your craftsmanship, skill and problem solving is brilliant but for me it pales into comparison of the sheer effort and resilience you have doing this. Seriously, if ever you need to find a New Job, show the employer this vid. I have run businesses and if someone said this is my resume, it would be the last one I'd look at and you'd be hired then and there. Says loads about the man you are and definitely the sort of bloke I'd want with me.
When you were talking about the weight on the pipes, an IBC was what I thought of. That fact that's what you did gives me comfort a smart man had the same Idea..... although I didn't think of stacking 2 but shows you are also braver than I. I think you can stack 4 of them in their weight rating... But I wouldn't recommend that in this case. :0)
One thing I did think of with the digging particularly horizontal, would be to use an Auger. I have a petrol Post Hole Digger and boring a load of holes like a Swiss Cheese and then breaking the walls out between I have found is much easier for me than just digging with a shovel. If there was a Drill for your Hydraulic pump, that may be worth considering.
That said. I was amazed in the shot of you digging the clay. Sounded like you were digging Concrete!
You won't need to reinforce the Tunnel walls. Just light a good hot fire and bake them and you will have Terra cotta!
Far from a disappointing vid mate. Awe inspiring for me in your creativity with problem solving and the sheer bloody effort resilience you have. Fking champion in my book!
I don't think 4 ibc's is a problem, on the contrary I think it'd be fun trying!
I'll try and pick a few more up this week, maybe get some extra so I can pump between them rather than using a hose pipe as that takes a while.
Thanks as always for your motivational words and plugging my channel, it means a lot my friend.
You need a smaller scale experiment.. dig a hole use a 4 inch pipe check what happens
- It's not flotation. Looks like you hit a relatively solid strata.
- seems to me the easiest way to drain the water from outside the casing is to drill a small channel parallel to the casing deep enough for water pressure to break through and drain to the interior, where you can run the pump.
If it's not flotation is there any need to drain? I'd rather leave the seal in place to minimise future moisture ingress
Godspeed! I know it's been a while but you're making progress at the grind.
Cheers mate
would aerating the water not help it sink ?
I'll put it on my list of things to try
F*$King trains lol .I think that sump turned out well James and the more you do the better you will get so I think you should do all your castings instead of buying them in all ready made as it will be cheaper and every penny saved. Things really seem to be moving on quickly now it's amazing that you have achieved all this single handed. You really are one of akind James keep it up mate your doing what many can only dream of. Take care till next time my hero. 👍👍👍
I suppose if I made the sumps in two parts I could make permanent moulds, it's time though mate, just slipping through my fingers, can't believe we're approaching august.
with the pressure pump you are building what you use is air not water the air acts as a piston and each bubble carries water with it and it will carry the rubbish with it or you could use a clam shell
In your thumbnail you look like THX trying to keep ahead of the Android cops lol.
Going well 👍
Cheers mate
What about driving/firing a big 'ancor' into the bottom of the hole and using that to winch the pipes down into the ground
It's a technically challenging idea but the ground at the bottom is very solid and I have a 3 ton come-along, one of craziest ideas that I think would actually work so far, nice one.
@@turboconqueringmegaeagle9006 nice one! A 3 Tonne would be a right pull. I see theres such a thing as a ground anchor auger might give a good enough hold if it can be drilled in.
Good choice from your humours friend
Cheers mate
How about hiring a high frequency concrete poker and sinking it in the clay at the bottom,?
I've actually just got one to run off my compressor, giant d1ldo looking thing, I'll try it mate nice one.
Stacking IBCs that’s mad! 😀
nice to see you back
Hello Dee, nice to see you too
@@turboconqueringmegaeagle9006 nice to see new videos as its been so long without seeing no videos
Go drop one of those rings in a river M8 see if it floats LOL if it does see how long before it sinks if it floats its that porous it woulda crumbled by now M8 it ain't made of pumice I hope
Nah, it's a beautiful bit of concrete, no reinforcement but they've obviously used granite fines or something.
Entire video I sat here going "What in the fuck is he doing? Why IBC totes on TOP of it? This guy is so dumb...?" Then I realize you're smarter than me. Well done, sir.
@26:40 were you whistling the tune from Tetris?
Yes I was!
Quality!
Cheers mate
Nice hole.
james , ive been watching another shelter vid , and hes coated his concrete in tar to waterproof it , just wondering is that no good for you mate ?
It would have gotten damaged as the pipe slid down so I used sodium silicate.
What's the other channel called mate?
cant find a link to send it , but his name is james diesel , try that mat
mate
@@davidevans4750 yeah that's a nice bunker, can't remember the bitumen, I'll have to rewatch it. My favorite bit of that build was his muck removal railway, really cool.
What if the pipes keep sinking... and sinking? and sinking?
It's such hard clay down there I don't think I need to worry about that but I'll be pouring some concrete at the top and bottom to make sure
Could you not jerry-rig some sort of slide-hammer off those lifting mounts you already have in every one of those pipes, leave it going like some nodding donkey?
If it was steel pipe id like that idea, but that sounds bloody dodgy with concrete and my mortar joints
@@turboconqueringmegaeagle9006 I should clarify that I meant it as more of an agitator/vibration than a give it some welly type of thing with it being concrete :D
You have me baffled, You think those rings want to float? not a chance you need to get a slew or 360 machine and a bloody good driver dig round the rings you ain't gonna puddle th clay round them till your down t lvl and water pressure won't stop em sinking.
I was reading straight from the American association of concrete pipes, and my pipes definitely displace more than they weigh. Either way even if it's just for the backfill, I need the water gone at some point.
@@turboconqueringmegaeagle9006 If they were led flat maybe but not vertical M8 I put god knows how many of those rings in the ground I ain't wrong. if you dig round those rings as you shoulda done from the start you could fill that extra-large hole with water and those rings would sink to the bottom no problem and you said you were gonna puddle blue clay round the finished job for waterproofing
@@nigelpalmer9248 mate, everything you've ever commented has been golden, just telling you what I've read and probably misunderstood.
I'll try stacking some more weight up top.
Dooler!!!
Alright my friend
Stackable IBC’s = cheap easy manageable weight
I messaged as watching lol then he drags IBC into shot, great minds think alike
Ha, nice one
James you made a lovely mobile compressor, why are you not using it to pump that water out
Copy the brumby pump or another dirty bore well air driven pump
@@Steveom yup, I should be, the timeline is all disjointed though most of this happened before I finished the compressor
Buy a bloody ladder 😆
Alright mate, howsit going?
@@turboconqueringmegaeagle9006 terrible lol sorry not been supportive chap my mum's gotten Alzheimers my hearts bad and I'm depressed apart from that lol I'm glad your ok and doing well I hope you get this all done with and are chilling in a new subterranean workshop soon. 😉👌
